Jesse wants to have a romantic night with Becky, who tells Jesse that she can't because she is scheduled for a business dinner with Beau McIntyre, a former football player who is scheduled to be a guest on Wake Up, San Francisco, and that makes Jesse jealous.
Joey, who is preoccupied with his new car "Rosie," a 1963 rambler. When he sees a nick in Rosie's paint, he leaves with Comet to go to Sid & Jean's Auto Supplies to buy a bottle of touch-up paint. While Joey is gone, Stephanie gets inside of "Rosie" so she will have something to do.
As she is sitting in the driver's seat, she decides to turn the radio on; it does not come on, so she turns the key, hoping that she is turning it toward the auxiliary option that allows you to turn on the radio while the car is not running. Instead, she ends up starting the car. Not knowing what the letters and numbers on the gear lever mean, she thinks the letter R means "radio," so she puts it on "R", discovering the hard way that "R" means reverse, as "Rosie" backs up and crashes into the kitchen. She is so terrified and feels so bad about it that she has her ride to dance class drop her off at Becky's house on the way home, and Stephanie tells Becky that she can never go back home.
Jesse shows up at Becky's house to apologize for being jealous, and he talks to Stephanie, who is afraid Danny will stop loving her when he sees what she has done. At home, Danny proves her wrong. Although Danny is indeed angry about the mess, he promises that there is nothing she could ever do that would make him stop loving her.
